Peel the bananas and cut each one in half crosswise to make four pieces.

Insert one popsicle stick into the cut end of each banana half.

Spoon the vanilla yogurt into a small bowl and stir it until smooth.

Dip each banana pop into the yogurt, turning it to coat all sides evenly.

Place the coated pops on a parchment-lined tray and add mini chocolate chips to form eyes and a mouth on each one.

Transfer the tray to the freezer and leave the pops until the yogurt is firm, about two hours.
